Description
Technical field
The invention belongs to mining technical fields, and in particular to a kind of for improving the side of underground stope ore removal efficiency
Method.
Background technique
Underground stope ore removal efficiency and the demolition effect of mining, ore removal equipment, pavement behavior, transportation range, activity duration
It is related with pavement behavior, transportation range, activity duration in the case where demolition effect, ore removal equipment are certain etc. related.
Traditional downdraft mode sublevel caving arranges connection roadway 8 outside arteries and veins, ore pass 6 and arteries and veins outside arteries and veins in stope
Outer talent's well 11, according to height of lift back production from top to bottom.Connection roadway outside arteries and veins is arranged other than ore limits, is got in touch with outside arteries and veins
Ore pass outside an arteries and veins is arranged at interval of 50m on tunnel.Ore removal equipment shovel at the quick-fried heap of stope drift active workings mining takes ore, through back production
Tunnel, the outer connection roadway of arteries and veins are transported to the outer ore pass of arteries and veins.When quick-fried heap encounters lump ore, stop ore removal operation, to lump ore
Second-time breakage is carried out using blasting method.
The presence of above-mentioned tradition ore drawing in stope mode is the disadvantage is that transportation range is long, pavement behavior is poor, breaking up of boulders, often
Safe ventilation after secondary second-time breakage reduces the activity duration, causes to directly affect to ore drawing in stope efficiency, safety in production.
Summary of the invention
The object of the present invention is to provide a kind of methods for improving underground stope ore removal efficiency.
In order to meet above-mentioned purpose, the technical scheme adopted by the invention is as follows:
A method of for improving underground stope ore removal efficiency comprising following methods:

At the both ends of measure connection roadway, measure ore pass, the measure ore pass and level haulage tunnel connection are set, it is described to arrange
The lower end for applying ore pass is equipped with vibration ore dumping machine;
B:Lump ore is set and stores chamber:The two sides of the stope drift active workings are provided with lump ore storage chamber, the bulk
Ore storage chamber is located at medium-length hole blasting between measure connection roadway;
C:Slag road surface is set:Slag road face is laid on the bottom plate of every stope drift active workings.
Preferably, width >=50m of stope described in A, the spacing between described two stope drift active workings are 10m, described same
5 stope drift active workings are disposed in one stope.
Preferably, the section of the stope drift active workings is arch, and the area of the stope drift active workings section is 8.54m2。
Preferably, the size of measure ore pass described in A(It is long × wide)For 2 × 3m, the bottom of the measure ore pass
Vibration ore dumping machine 9 is installed.
Preferably, the size of the storage of lump ore described in B chamber(Length × width × height)For 4 × 2 × 4m.
Preferably, slag road surface described in C passes through 1 using cement, gypsum, slag and water as material:0.75:3.5:0.6
The mixing of weight mix ratio, mechanical stirring is laid with after 2-3 minute, formation slag road surface after solidification.
Beneficial effects of the present invention are:
(1)Shorten transportation range:Inside stope, ore body middle position setting measure connecting taxiway, measure ore pass carry out fortune mine,
The outer connecting taxiway of setting arteries and veins, ore pass outside mine operation mode and stope is unloaded to carry out fortune mine, unload compared with mine operation mode, transport away from
From 60 ﹪ -70 ﹪ are shortened, the time for once transporting, unloading mine shortens 60 ﹪ -70 ﹪, and ore removal efficiency increases substantially.
(2)Increase the activity duration:When encountering lump ore during ore removal, lump ore scraper to lump ore is deposited
Chamber is put, concentration second-time breakage is carried out, stops ore removal when encountering lump ore with traditional, crumbling method phase is carried out on quick-fried heap
Compare, increase the activity duration, ore removal efficiency increases therewith.
(3)Improve the speed of travel of transporting equipment:Using cement, gypsum, slag etc. as material, it is laid with slag road surface,
With tradition on roadway floor compared with direct ore removal, slag evenness of road surface, intensity are high, and common roadway floor is uneven,
There are also a large amount of muddy water, is transported on slag road surface, unloads mine, improved traffic condition, improve equipment availability, while
Improve travelling speed.
(4)For the present invention by setting measure connection roadway, measure ore pass, setting lump ore stores chamber, setting mine
Slag road surface, shortens transportation range, increases the activity duration, improves the speed of travel of transporting equipment, and ore removal efficiency significantly mentions
It is high;Compared with traditional ore removal way, ore removal efficiency is increased to 120-130 Dun ∕ machine-team by 45-50 Dun ∕ machine-team.
